Audemars Piguet Royal Oak Double Balance Wheel Openworked ’Salmon’ Skeleton Stainless Steel, Pink Gold-Toned Openworked Dial with  Applied Hour-Markers and Royal Oak Luminescent Hands, AP Manufacture Calibre 3132 Self-Winding Automatic Movement, Sapphire Crystal Exhibition Case Back, Royal Oak Stainless Steel Bracelet with Double Fold-Over Deployant Buckle, 41mm

This Audemars Piguet Royal Oak Double Balance Wheel Openworked is powered by the in-house Audemars Piguet Caliber 3132 self-winding automatic movement. It is rhodium-plated, fully skeletonized, and meticulously hand-finished with Côtes de Genève, circular graining, and finely polished anglage. The caliber is composed of 245 parts with 38 jewels. Its most distinctive feature is the patented double balance wheel system, which mounts two balance wheels and two hairsprings on the same axis, significantly enhancing precision and stability by countering positional errors and reducing the effects of external disturbances. Regulation is achieved through variable inertia blocks rather than altering hairspring length, providing long-term stability. The balances oscillate at a frequency of 21,600 vph (3 Hz), with a stop-second device for precise time setting. A monobloc 22-carat gold rotor mounted on ceramic ball bearings ensures efficient bi-directional winding, delivering a power reserve of approximately 45 hours. Every visible surface of the bridges and mainplate is open-worked and decorated by hand, featuring polished bevels, interior and exterior angles, and contrasting satin and brushed textures, all designed to showcase both the artistry and mechanical complexity of the movement through the sapphire crystal dial side and case back.

The Audemars Piguet Royal Oak Double Balance Wheel Openworked ’Salmon’ Skeleton is one of the most visually captivating and technically sophisticated models in the Royal Oak collection. This striking timepiece blends avant-garde aesthetics with cutting-edge horology, embodying the spirit of modern luxury while preserving the heritage of Haute Horlogerie. The dial is openworked with a gold-toned architecture, revealing the full complexity of the mechanical heart. Every gear, bridge, and wheel is on display beneath sapphire glass, framed by the iconic octagonal bezel with hexagonal screws. The luminous white gold hands and applied indices ensure readability without compromising the skeletal aesthetic.
